Traditional Sash windows parts

The Sash window can be broken down into four primary components: the sash, the frame, the glass, and the hardware.

The sash is the dynamic section of the window, capable of opening and closing. The frame, in contrast, is the immobile portion of the window. The glass is the component that allows light to permeate into your home, while the hardware encompasses the elements that keep the window functioning, including locks, handles, sash window stops, fasteners, and pulleys.

Understanding the integral parts of your property’s sash windows is crucial, especially in the event of malfunction or damage that necessitates repair. This article provides a concise overview of the different elements constituting a sash window.

The Sashes

The sash is the operational part of the window, nestled within the frame, which holds the glazing and functions via a pulley and weight system. It’s the element that you manipulate to admit air into your house.

Sashes are typically of two kinds: single-hung and double-hung. Single-hung sashes feature one mobile panel and one stationary panel. On the other hand, double-hung sashes boast two mobile panels, enabling you to open either the top or bottom section of the window.

These sashes can either have single or double glazing, or if they are…

The Frame

The window frame, consisting of the sill, architraves, header and other components, is the static portion of the window. Its primary role is to offer structural support for the sashes. For classic box sash windows, the frame incorporates a pulley and weight system.

While traditional sash window frames are crafted from wood, contemporary designs often utilize materials like vinyl or aluminum. Wood remains the most prevalent choice due to its strength and durability. Even though vinyl and aluminum frames come at a lower cost, they tend to lack the aesthetic appeal of their wooden counterparts.

The Glass, single or double glazing

The glass component of your window is the conduit that allows natural light to flood into your home. Typically, traditional box sash windows feature single glazing, although many have been recently updated with double glazing for better insulation. Glazing bars, often referred to as muntins, secure the glass and segment the window into smaller panes. These bars contribute to the iconic aesthetic of sash windows. The glass is usually secured using either traditional putty or modern beading methods.

The Sash window hardware

The hardware of a sash window comprises elements such as locks, handles, sash stops, fasteners, and pulleys. Handles are utilized for opening and closing the window, while sash stops are designed to restrict the window from being opened excessively. Additionally, fasteners are employed to secure the sashes in place.

Can you repair or replace sash window parts?

Should you encounter any damage to your sash window components, rest assured they can be repaired. In case of a rotten window sill, it can be entirely replaced. Similarly, the cord and pulley system can be updated, and the glass panes can be swapped out. Given that the frame remains structurally sound, all other parts of the windows are replaceable or restorable.
